摘要：
A facility for positron annihilation induced Auger electron spectroscopy (PAES) was built up at the slow positron beam of the Technical University of Munich. The positron beam (intensity 10(4) e(+)/s, energy some 10 eV) is magnetically guided to the analysis chamber and then electrically focused onto the sample. Released Auger electrons are detected by an electrostatic hemispherical energy analyser with an energy resolution of about 3 eV. First measurements on annealed copper are presented and compared to conventional AES. (C) 2003 Elsevier Science Ltd. All rights reserved.
